Introduction

This demo requires the ACPLT/RTE to be running. The ACPLT/RTE works as a host for the Asset Administration Shells. Besides hosting AAS, the ACPLT/RTE provides functionality to access and manipulate data of the AAS. The structure is discoverable with standard OPC UA services. However, the message-based It also serves as a local evironment for message-based communication with the industrie 4.0 component.
With this repository you can create the needed structures for an Asset Administration Shell, i.e., overall Container, Property Value Statement lists with their statements, Life Cycle Archive and its entries.

This repository provides a project that creates a library which implements basic functionalty to create and delete asset administration shells and their inner objects (property value statements, lifecycle entries etc.). The library expects an OPC UA server on the other side that implements the OPC UA models that are provided in the models folder.
All interface functions depend only on basic c-datatypes. That allows to write simple wrapper for applications like libreoffice or excel to call this functions directly.
An example application openaas_eng shows how to use the library. Furthermore, within the libreoffice folder an example python script is delivered that uses the libopcua_interface library to create AAS objects. In that case, libreoffice can be used as a client to create asset administrations shells and their describing property value statements.

Requirements

The server: Linux (tested on Ubuntu 14.4) / Windows 7

The Engineering Client: (tested on Ubuntu 14.4)

Getting Started

Setting up the Server

Within this demo, it is assumed that the AAS are stored in a organization-bound repository which implements an OPC UA interface to interact with the AAS. In this example, the repository server is implemented with ACPLT/RTE. Compile it as described and add in the ov_server.conf following line at the end:

The ACPLT/RTE should now be available to be explored with ACPLT/KS (iFBsPro) or OPC UA (e.g., uaExpert). With uaExpert you should see a structure like that:

Setting up the Engineering Client

Download the client software

To download the full repository you have to clone it:

git clone --recursive https://github.com/acplt/openAAS_workshop

Building the client software

Configure the project with CMake

cmake .

Build it:

make

Afterwards you will get the library libopcua_interface.so that provides several OPC UA functions. A basic example application openaas_eng.c shows how to use these.

Installing the Python OPC-UA-openAAS-Interface

Install the python library for openAAS with pip3.4

cd python && sudo pip3.4 install -e .

Afterwards, you are able to use this library within other python scripts.

Using the LibreOffice Engineering Interface (Ubuntu)

If you have Ubuntu, LibreOffice is already installed and you can create the folders /Scripts/python within

~/.config/libreoffice/<version>/user/

and copy opcua_interface.py to:

~/.config/libreoffice/<version>/user/Scripts/python

Afterwards, start the ACPLT/RTE with the openAAS Library. Now, you can open the provided LibreOffice Calc file (aas_client.ods) from /libreOffice folder and start to create AAS, Property Value Statements and Lifecycle-Entries.

You need to activate python macro support in libreoffice:
